Tattoos are actually a kind of minimally invasive skin coloring. It is not clear whether they belong to medical beauty or life beauty. Is to implant pigment into skin tissue to form a stable color block. Because the epidermis is very thin and translucent, the implanted pigment presents the implanted color through the epidermis, thus covering up the defects, fostering strengths and avoiding weaknesses, and playing a beautification role.

Because the pigments infiltrated into the skin are small particles with a diameter less than 1 micron, they are quickly surrounded by collagen after implantation, but they will not be swallowed up by cells, thus forming semi-permanent marks on the skin surface. It is also called "embroidery" or "Wen Xiu" or "Shi Wen". Modern tattoos include three items: eyebrow tattoo, floating lip tattoo and eyeliner tattoo.

The process of tattooing is to directly pierce the skin and inject pigment, so as a qualified beautician, you should have strict disinfection and hygiene concepts. The effect of medical beauty is not good, which may be related to inadequate disinfection and sterilization. Find a way to remedy it after you find it.

When the whole lip surface is colored, the upper and lower lip surfaces are divided into four areas, and each area can be divided into 2~3 pieces according to the number of needles of the eyebrow tattooing machine. When operating, carefully pattern each piece before proceeding to the next piece.

When making a lip liner, we should take a sectional treatment, that is, divide the lip liner into several sections and transport the needles one by one. When making lip liner pens, you should always contact the coloring materials to ensure smooth color flow. If there is bleeding or pigment accumulation, you should avoid this place and replenish the needle when coloring next time.

Customers who have tattooed their eyebrows before, tattooed their eyeliner or lip liner, some colors become abnormal, some shapes are out of date, and some customers repeatedly tattooed, washed and cut their eyebrows, resulting in pigment residue and scar hyperplasia. These situations all belong to the scope of modifying tattoos.

Generally speaking, skin is divided into epidermis and dermis, and its thickness varies from 0.2 12 mm to 0.508 mm according to different parts, with the thinnest in the eyes and the thickest in the palm. Knowing the thickness of the skin and the depth of the needle when tattooing, we will be sure that the tattoo will not be too deep or too shallow.
